"A total of 32 sediment samples were collected from the Ottawa River, Lac des Deux Montagnes, Lac Saint Louis and Canal de Beauharnois for toxicity screening tests and ATP (biomass) concentrations. Within Lac Saint Louis, the distribution and concentration of toxicants and ATP concentrations were similar to those found in the 1984 study of this area. There appears to be a band of sediments between Ile de la Paix and the south shore of Lac Saint Louis where toxicants are readily found. No toxicants as measured by the Microtox procedure were found in sediment samples from the Ottawa River and Lac des Deux-Montagnes"--Abstract. Includes abstract in French.
